UNLOCK // PDA CASE FILE
Can't Unlock the Mobile Vehicle Bay in Subnautica
The Mobile Vehicle Bay is a three-fragment deployable blueprint. If vehicles are still unavailable, check the fragment count and search the early wreck routes instead of waiting for a story unlock.
LAST CHECK
ANSWER LOCK // QUICK RESPONSE
Scan three Mobile Vehicle Bay fragments. Official Wiki locations include wrecks and crates in the Kelp Forest, Grassy Plateaus, and Safe Shallows; once complete, craft the deployable from the Fabricator.
